Motor-driven camera

Abstract

Abstract PURPOSE:To realize the miniaturization of a motor-driven camera, by using the ratation of a motor incorporated into a spool for motive power of various mechanisms of a counter, shutter resetting and film rewinding via a sprocket shaft. CONSTITUTION:A stator is used as a spool 2, and a rotor is incorporated into the spool 2. Plural pawls 3 are provided at the lower part of the spool 2, and perforations 4a of a film 4 are fitted to these pawls. A shift 5 is provided in parallel to the spool 2, and guide roller support arms 6 and 7 are born rotatably at the upper and lower parts of the shaft 5. The upper arm 6 is energized counterclockwise by a spring 8 to press a guide roller 9 which is attached at the tip of the arm 6 to the outer circumference face of the spool 2. As a result, the sag of the film which is rolled round the outer circumference of the spool 2 can be prevented.
